What do candles do?
As you know, a spark plug supplies a spark to the cylinder to ignite the fuel inside the combustion chamber. The spark plug is exposed to enormous temperatures, which of course does not have a favorable effect on its condition, so neglecting to replace spark plugs is highly discouraged and, if possible, it is advisable to change them before winter for easier starting in cold weather.
A worn-out spark plug can cause a lot of trouble, such as a lot of engine tripping, a number of misfires, loss of power and even an increase in fuel consumption.
In this article you will find the answer to the question of which spark plugs are best suitable for the Lada Niva.
Selection options
No one has yet invented standard SZ that are suitable for absolutely all cars, so it is clear that on a Chevrolet Niva you will have to select devices based on two indicators:
- heat number;
- geometric size.
The first indicator indicates the operating temperature of the product. The higher the value, the colder the product. This means that work can also be done in unfavorable environments where the temperature is elevated. If the heat value is low, this means that the SZ is hot and will often overheat. If it overheats, it will not last long.
Size plays an important role, that much is clear. If its size is small, the part simply will not screw into the socket and then the electrodes will be at a great distance from the combustion chamber. If the length is longer than necessary, then the electrodes will stick out, and this increases the risk of contact with the piston. When choosing, it is best to use the instructions from the car, which will tell you which spark plugs to install in the Chevrolet Niva. In addition, knowing the exact size, you can choose the best heat rating (video author - VanLe9).
It is recommended to replace it every 30 thousand, and the recommended imported analogue is the BRISK Super LR15YC spark plug, or LR17YC - this is for winter. However, in terms of price/quality ratio, there are now more interesting options. At one time, one authoritative publication compared 9 replacement options. But the reader will not immediately know which spark plugs work best on a Chevrolet Niva: if you buy the “best” BOSCH Platinum spark plugs, cold starts will become problematic.
We watch a video with conflicting reviews about NGK brand products.
It’s worth noting right away that not a single manufacturer has yet created a spark plug option that will fit any engine. Each motor has its own model. This must be taken into account if the time has come to change them. When selecting the optimal option, two most important selection criteria should be taken into account:
- Heat number is the temperature value for efficient operation. The higher this indicator, the colder the part remains during the operation of the car. This parameter demonstrates the ability to operate effectively in the most unfavorable environment - at high temperatures. The lower this indicator, the more often the part will overheat. This significantly reduces its service life.
- Geometric size - different brands and models of cars use a certain type of spark plug, which has its own thread length, number of electrodes, and size of the spark plug key.
Without knowing which spark plugs are best for a Chevrolet, it is recommended that you read the vehicle’s operating instructions. It clearly states the size and type. Knowing them, it will be possible to select options with the optimal heat rating.
New spark plugs will help get rid of many problems with your car.
Spark plug gap on Niva
The gap between the electrodes on the spark plugs is one of the main indicators that directly affects the operation of this engine part. It must be checked every 20-25 thousand km to ensure proper engine operation. The gap can be adjusted if it is out of the normal range or it is better to replace the spark plugs with new ones.
The normal gap on Niva spark plugs is 1.1-1.2 mm.
Expert recommendations
None It is important to consider some differences when choosing a SZ:
- EZ A17DVRM consists of Russian-made parts;
- APS A17DVRM consist of German-made parts.
To avoid confusion, you should always look closely at the markings. Speaking about the second option, one must also take into account the fact that APS A17DVRM are manufactured using advanced technologies. Among other things, they are distinguished by better processing of the electrodes, and therefore you can avoid problems with a running spark, which is typical for defective devices.
When choosing suitable products, you need to follow some rules:
- DENSO IW20 and NGK devices contain a sufficient amount of iridium, which has a beneficial effect on engine life.
- BOSCH WR78X parts accommodate four electrodes.
- GM WR8DCX are suitable for use in winter and summer. They are preferable to the aforementioned A17.
Niva's original spark plugs
The Niva is supplied from the factory with domestic spark plugs from the Engel plant, which specializes in the production of automotive spark plugs. The plant installs AU17DVRM brand spark plugs; these plugs have proven themselves well and meet all quality standards and service life.
A large number of analogues of these spark plugs have appeared on the market, which are no worse than factory ones, and sometimes even better. Analogues of candles can be both imported and domestic.
Below is a table of spark plugs suitable for a Niva car from well-known brands such as DENSO, BOSCH and Brisk.
LADA spark plugs: top 10 options
The rating contains 10 modifications of spark plugs, without division into specific car models.
10th place: ZZ A17 DVRM
The list of the best offers opens with an effective model that is in demand among a large number of buyers. Such prevalence is ensured by the stable quality of products. In the original packaging it is impossible to find a defective part or a spark plug with a broken gap. A significant advantage of the products is the ability to work actively even when the voltage drops to 6V in the on-board network. Similar spark plugs in the VAZ 2107 are often found due to their moderate cost.
The indicators are overshadowed by bad statistics - as of 2020, 35% of the kits on the market are fakes, which forces motorists to carefully select products in stores.
- reasonable price;
- durable;
- simple design.
- plenty of fakes.
9th place: TZ 17 DVRM
The next representative of the rating implies the presence of as many as three electrodes on the working part of the device. A large number of motorists install such spark plugs on a VAZ carburetor or even an injection type. Thanks to the use of advanced developments in design, the manufacturer has increased the service life of the electrode.
Pirate copies also play a role here - there are a large number of them, which makes buyers cautious about purchasing products.
- good performance;
- long period of operation;
- wide use.
- there are fakes.
8th place: DENSO W20EPR-U11
If you want to buy VAZ injector spark plugs, you can turn to the eighth position of the rating. Candles represent a compromise between high quality and moderate cost. Thanks to this symbiosis, such spark plugs are perfect for the VAZ 2106. Also, this model will be relevant for more modern versions. It uses technology to increase spark stability. The development significantly increases the service life of the part, which helps save on vehicle servicing. This also made it possible to reduce the maximum voltage drop to 6.5 V, which is less than that of Russian analogues, but thanks to stability, the spark plugs win positions.
- stable operation during voltage fluctuations in the on-board network;
- long service life.
7th place: BRISK LR15YCY-1
The next contender for the title of best is distinguished by an increased overhang of the working part. The specified spark plugs for the VAZ 2107 carburetor are ideal. The standard eight-valve engine works great with the included model.
In terms of performance parameters, the model is a confident average and can be used even on used foreign cars with similar engines. The ability to work on a dead battery has also been developed. The product is capable of igniting the mixture even at 6.2 V within the network, which is significantly better than the performance of competitors’ analogues. Buyers consider the rather high cost to be the only serious disadvantage.
- increased resource;
- sufficient versatility;
- The gap fits well with classic engines.
- high price;
- difficult to find - not very common.
The best candles for Niva
Based on reviews from forums, it has been repeatedly revealed that Nivovody gives their preference to NGK candles. These spark plugs are excellent for the Niva engine and can withstand high temperature loads. NGK spark plugs make it easier to start the engine in cold weather and even reduce fuel consumption due to their structure. The closest to standard spark plugs and suitable in design to the Niva engine will be NGK No. 11 spark plugs.
These spark plugs easily overcome the 30,000 km barrier without any damage.

Types of spark plugs for Russian SUV
Original Bosch spark plug
So, you have carried out diagnostics and come to the conclusion that your car does not require repair. Which spark plugs to choose if you only need to replace them? Since we are talking about the Niva Chevrolet model, it makes no sense to consider the option for a carburetor car. For the injector, you can choose one of the three most popular kits.
Most often, spark plugs are used, which are recommended for 8-valve injection engines. The optimal gap between the electrodes is 1.1 mm. It is necessary to ensure that it does not exceed 1.5 mm, otherwise the spark plugs will fail. Low-quality fuel will also be detrimental to them. Advantages: low price, long service life.
Plugs with a platinum coating on the center electrode last even longer. This is their main advantage. Without damage to the electrode, provided that good fuel is used, they are able to work until the car travels about 50 thousand km. Conventional spark plugs will have to be changed after 10-15 thousand km, because the central electrode is knocked out by a spark and the gap increases.
Multi-contact spark plugs are ideal for the Niva Chevrolet, which is actively used in severe frost conditions. The main advantage is trouble-free engine starting early in the morning. These candles can only be used in winter and replaced with regular ones in summer.
Engine diagnostics based on spark plug condition
For the 2111 engine, the balance of forces looks like this:
- BOSCH Platinum WR7DPX
- "EZ" T17DVRM 1.0 (3 electrodes)
- NGK BPR6ES-11
- DENSO W20EPR-U11
- Ween 121-1370/KMR6C11
- BERU 14R-7DUX
- BRISK Super LR15YC
- Hola BH7CR11
- "Citron" A17DVRM
Based on this list, it is impossible to say which spark plugs are best for the Chevrolet Niva. What works best for one 8 valve (1.6) may not work for another (1.7).
The products of the Japanese brand DENSO were popular, but counterfeits began to appear, and now budget DENSO candles are no longer sold at all.
Inspecting the spark plugs can help you identify some engine malfunctions without contacting a special service center. Particular attention should be paid to the appearance and color of soot. The normal condition of a spark plug that does not require replacement is moderate burnout of the electrode, a complete absence of oil stains, as well as a minimal amount of soot and coffee-golden deposits on the insulator. In this case, the Chevrolet Niva does not require constant topping up of oil and does not frighten the owner with its brutal appetite.
If you find black carbon and dry soot on the center electrode, most likely your car is consuming much more fuel than you would like. The reason may be a malfunction of the air damper drive mechanism or injector, or a clogged air filter. In general, this indicates a failure in the engine management system.
The engine is healthy - so are the spark plugs

DIY replacement instructions
To dismantle, first of all you will need a special key for removing the SZ. First you need to remove the ends of the wires from the spark plugs and clean all contacts from dust. The entire spark plug and the area around it must be thoroughly cleaned to prevent debris from getting into the cylinder.
Next, you need to remove the devices with a key and visually diagnose them for damage. You need to inspect both the electrodes and the threads. If there is noticeable darkening on the NW, it’s okay, but if there is no brownish coating, you should be alarmed. If black plaque is found, it must be removed. It indicates that engine oil has entered the engine cylinder.

When replacing, be sure to check the gap on the new SZ. If it doesn't quite fit, you can carefully bend the electrode on the side. This is a rather risky method, because you need to be as careful as possible and not damage the central electrode. Otherwise, the SZ will fail. After preparing the socket for the SZ, you need to insert it and tighten it with your fingers, and then tighten it with a wrench. Be careful here, otherwise the thread may break.

spark plugs for the Niva family
- Spark plugs for carburetor cars. The factory gap between the electrodes is 0.7 mm. I will not describe all the marketing gimmicks that the manufacturer writes, just high-quality spark plugs that maintain their required engine hours. Frequently asked question: the contact ignition system has been replaced. A distributor with a hall sensor, a switch and a coil from 2108 are installed. What spark plugs should I use? I experimented with this issue several times. I decided for myself: regular carburetor spark plugs with a slightly increased gap, literally by 0.1-0.2 mm. Produced in Germany.
- Spark plugs recommended by the manufacturer for 8 valve injectors, including for the Niva-Shniva family. The established gap between the electrodes is 1.1 mm. In the case of these candles, it would be fairer to say “workhorse”. Nothing outstanding, but they work until either diesel fuel is poured into the tank, or the gap increases to 1.5 mm. Bosch located the production of these candles in Russia, which, unlike other manufacturers, had a very positive effect on the price.
- A spark plug with a central electrode coated with platinum. Named . I’ll dispel the common myth that you install “platinum” or “iridium” spark plugs and the horn will fly like an airplane. The main advantage of these candles is their RESOURCE. When you install ordinary spark plugs, after 10-15 thousand the gap between the electrodes “goes away” due to the “knocking out” of the central electrode by a spark. According to my observations, with good gasoline, “platinum” spark plugs, without deteriorating their parameters, have a resource of more than 50 thousand km. Produced in Germany.
- Multi-contact spark plugs. In this case, four-pin. For a long time I could not clearly explain to clients what the “raisin” of the issue was. I will not repeat the nonsense that is said in stores and markets. The answer came when a batch of candles was sent to Yakutsk, to the same “junior-experimenter” like myself. It was a completely different SUV, but then this was confirmed in our cars. Their main advantage is starting the engine in the morning in very cold conditions. This has led to some of my clients installing "seasonal" candles on their cars. In summer they are ordinary, in winter they are multi-contact. Candles are made in Germany.
To carry out diagnostics, you will need a special wrench for turning it out. Please note that it is better to inspect the spark plugs after the engine has been running for a long time, for example, after a long trip on a country highway. If you have never replaced this small but important part in a Chevy Niva before, follow these simple tips.
A spark plug that produces the right spark
- Remove the high-voltage wire tips from the spark plugs.
- Clean the part and the area around it so that when turning it out, dirt does not get into the cylinder.
- Using a wrench, remove the spark plugs from the cylinder head.
- Examine the candles. Based on the degree of carbon deposits, its color and character, you can diagnose the engine and determine whether it is worth changing the part, buying gasoline at another gas station, or whether it is time to repair the cylinder head.
- Use a round feeler gauge to check the gap between the electrodes. It should be 1-1.15 mm.
- If necessary, bend the side electrode and adjust the gap between the electrodes. Be careful: under no circumstances should the central electrode be bent! This can lead to damage to the insulator and inevitable failure of the spark plug.
- Reinstall the candles. To do this, first screw them all the way by hand, and then tighten them with a wrench. Do not overdo it!
Signs that you need to replace spark plugs on a Chevrolet Niva:
- The power unit starts with difficulty. Long cranking of the starter is required;
- The feeling that the engine is not working at full strength;
- The characteristic sound of an engine running on three cylinders;
- Increased fuel consumption;
- Low power.

Good afternoon everyone, I would like to hear feedback on the use of various spark plugs in our cars. Who is “lighting” which ones and what’s the catch?
I’ll start with myself - I bought the car with EZ A17DVRM immediately after running it in (2 thousand km), changed it to BPR6ES11 , 10 thousand became unstable XX. Changed it to DENSO W20TT - now 31 thousand km. — the engine works well.
However, winter is coming. Maybe it needs to be changed - who will say what? I myself am looking towards multi-electrode ones: either BERU Ultra X or BERU Ultra X Platin or BERU UXT6
or W20EPBR-S - I doubt them and the gap of 0.85 is too small for the injector, or NGK BUR6ET - similar problem with the gap.

Engine 1.6 carb OZONE, new wires are not oak (700 rubles). gas station 92. company 2000 I’ll tell you from personal experience.
1) Brisk candles - 170 rubles (4 pieces), in winter they start the car -30, the car runs well, the mileage of the candles is short, they quickly fail. Replace every 2000-5000. They are very afraid of soot. 2) Champion candles (Champion) - 330 rubles (4 pieces), start the car the same way - 30, the car runs exactly the same, The mileage of the candles is average, replacement every 5000, although I change 1 candle at a time due to carbon deposits, I just throw it away. Although it could be a candle OK.
I put the brisk together with the champion, they work the same way. It’s not a fact that brisque dies quickly, I used briskies mainly in winter. The consumption is the same. PS: You can clean the spark plugs with a can (Carburator Cleaner)
